StandardConverter Class Reference


Implements the interface ObjectConverter. Class TextLogger creates an instance of this type in the moment no other (custom) type was set prior to the first log statement.

This implementation uses two specialisations of class Formatter to format the given logables to a textual representation. The formatters (and their sequence!) are:

  1. FormatterPythonStyle
  2. FormatterJavaStyle

This way, standard text logging supports format strings in Python style as well as in Java style.

◆ cntRecursionx

int cntRecursionx

A counter to detect recursive calls.

◆ Formatters

std::vector<Formatter*> Formatters

A list of formatters used to "convert" logables to strings. By default, each entry contains a concatenated pair of formatters of types FormatterPythonStyle and FormatterJavaStyle are added in the constructor of this class.

A vector of formatter is needed to support recursive log calls. If recursion occurs during logging (aka the conversion of a logable triggers another logging operation), necessary formatters are created on the fly, respectively re-used from previous recursions. Their settings are cloned to those of the main formatters using Formatter::CloneSettings .

The formatters created internally are set to unsafe locking mode (locking is switched-off). This is a small optimization and allowed due to the fact that class Lox is already thread-safe.

To use different formatters, it is recommended to implement a different converter type, instead of "patching" the linked and recursive formatters found in this vector.

Method Details:

◆ ConvertObjects()

void ConvertObjects ( AString & target,
Boxes & logables )

The conversion method. Passes target and logables to the Formatters.

targetAn AString that takes the result.
logablesThe objects to convert.

Implements ObjectConverter.

Definition at line 74 of file textlogger.cpp.

◆ GetAutoSizes()

AutoSizes * GetAutoSizes ( )

Checks if the first formatter in Formatters is of type FormatterPythonStyle . If so, its AutoSizes member is returned. If not, the method returns nullptr.

The auto sizes object of the main formatter.

Implements ObjectConverter.

Definition at line 114 of file textlogger.cpp.

◆ ResetAutoSizes()

void ResetAutoSizes ( )

Resets automatically widened tab stops and field widths of this converter.

Implements ObjectConverter.
